How to model limit the maximum force taken by a spring?

[jackyyau]

SAP2000 is able to model supports as springs. But does SAP2000 allow the failure of a spring?

For an example, if the spring is under tension and subjected to a force larger than its capacity, the spring breaks and the force previously taken by it will transfer to its neighbouring springs.

How can these springs be modelled???

In version 8, SAP2000 allows you define and assign multi-linear elastic springs or plastic springs using Plastic (kinematic) link option, both options using force-deformation.

With previous versions, you would have to use the Plastic1 nllink and input yield strength and post yield strength info.
